The problem with the United Nations is they propose that governments should regulate production and consumption in order to reduce GHGs. This socialist approach doesn't even work in countries like China and Russa nevermind capitalist countries like the United States. As we saw with vaccine production, if you monitize technology the private sector can respond quickly and efficiently. There needs to be more work at the U.N. to bring in private sector business to solve the problem, instead trying to get states to move to socialist regulation. This approach will simply destroy the economies of countries before any meaniful change can be accomplished.
